This page gathers peer-reviewed research studies and scholarly articles that explore various aspects of equine veterinary care, including advancements in diagnostic techniques, treatment protocols, and health management strategies to support the well-being and performance of horses.
Periodontal structures in horses with pituitary pars intermedia dysfunction: A histological evaluation. Pituitary pars intermedia dysfunction (PPID) and dental disorders are of major concern in horses older than 15 years. Although PPID in geriatric horses and dental disorders in all age groups are well described, a connection between this endocrine disease and pathological changes in equine dental structures has not yet been investigated. In humans, periodontitis is considered to be a complication of systemic diseases like diabetes mellitus type 2, obesity and various conditions leading to an impaired immune response. In PPID, cross links to insulin and immune dysregulations are proven. The aim ...
Does colonization with MRSA, ESBL – producing Enterobacteriaceae, and/or Acinetobacter baumannii – increase the risk for postoperative surgical site infection? Evaluation of the role of indicator pathogens in equine surgical site infection (SSI) and other infection-promoting factors. Cross-sectional study. Horses presenting with an open injury or surgical colic during 1.5 years. A nasal swab and a faecal sample were collected from every patient upon admission. Furthermore, a wound swab was collected from wounds of injured horses. Details on the wounds and procedures were documented.

Differential Expression of Innate and Adaptive Immune Genes during Acute Physical Exercise in American Quarter Horses. Overtraining syndrome (OTS) is the reduction in performance due to excess training and lack of proper recovery, which can lead to a chronic deprivation of energy and reduction in the repair of damage that can accumulate over time. Here, the effect of acute, intense physical exercise on the expression of innate and adaptive immune genes in 12 racing-bred American Quarter Horses, after resting for 3 days and immediately after intense exercise for 1.8 miles were compared. The expression of 84 genes related to innate and adaptive immune responses was analyzed. Significant variation among individua...
Use of a new device for inversion of the necrotic ileal stump in the caecum in four horses. In jejunocaecal anastomosis leaving a necrotic ileal stump has been implicated in complications and poor outcomes. Elective inversion of the necrotic stump using a nasogastric tube has been previously described, although this procedure can be cumbersome and can cause caecocolic orifice occlusion. Objective: To describe the use of a new device for elective inversion of necrotic ileal stumps. Methods: Case report. Methods: Details of the four horses that underwent intestinal resection and anastomosis with elective inversion of the ileal stump were retrieved from their medical records. For each c...
Development of a laparoscopic technique for inguinal hernioplasty in standing horses. Most previously described techniques for laparoscopic inguinal hernioplasty (IH) in horses require advanced laparoscopic skills. Our objective was to describe a new laparoscopic IH technique using a surgical anchoring system. Methods: Standing laparoscopic IH was performed unilaterally in eight experimental stallions, using the contralateral inguinal canal (IC) as a control. A polyether ether ketone harpoon was anchored in the craniolateral aspect of the vaginal ring, and an extracorporeal knot was used to fix the device. Clinical evaluation, including testicular palpation and lameness examina...
Proximal Interphalangeal Arthrodesis in Horses: A Meta-Analysis of Retrospective Studies.

Objective: The aim of this study was to i) develop and validate tools to detect, isolate and identify different Mycoplasma spp. strains in clinical equine respiratory-tract specimens and ii) subsequently define the prevalence of the three species ...
Association of globulin concentrations with prognosis in horses with lymphoma. Lymphoma is the most common hemopoietic neoplasia in horses. Common clinicopathologic abnormalities in equine lymphoma include hyperglobulinemia, hypoalbuminemia, hyperfibrinogenemia, anemia, thrombocytopenia and lymphocytosis. Hypoglobulinemia has been reported in other species with lymphoma, however it has not been well-described in horses. The objectives of this study were to examine the prevalence of hypoglobulinemia in equine lymphoma, and to identify prognosis and clinicopathological abnormalities associated with serum globulin concentrations. Unassigned: Ninety-six horses with lymphoma ...
Biomarkers of Intestinal Injury in Colic. Biomarkers are typically proteins, enzymes, or other molecular changes that are elevated or decreased in body fluids during the course of inflammation or disease. Biomarkers pose an extremely attractive tool for establishing diagnoses and prognoses of equine gastrointestinal colic, one of the most prevalent causes of morbidity and mortality in horses. This topic has received increasing attention because early diagnosis of some forms of severe colic, such as intestinal ischemia, would create opportunities for rapid interventions that would likely improve case outcomes. This review explores biom...
Total Carbon Dioxide (TCO2) Concentrations in Thoroughbred and Quarter Racehorses in Louisiana. The TCO (total carbon dioxide) test is performed on the blood of racehorses as a means of combatting the practice of administering alkalizing agents. This study evaluated serum TCO concentrations and factors influencing concentration of TCO in Thoroughbred and Quarter Horses. The normality of data were evaluated with a Shapiro-Wilk test. Mann-Whitney tests and Kruskal-Wallis tests were used against different effects. When a fixed effect was detected, Dunn's post-hoc comparisons were performed. The median pre-race serum TCO concentration (32.20 mmol/L (interquartile range (IQR): 30.80-33.50)) w...
An Overview of Factors Affecting Exposure Level in Digital Detector Systems and their Relevance in Constructing Exposure Tables in Equine Digital Radiography. The aim of this review is to describe the steps of constructing exposure tables for use of digital detector systems (DRx) in equine practice. Introductory, selected underlying technical aspects of digital radiography are illustrated. Unlike screen-film radiography (SFR), DRx have a uniform signal response of the detector over a large dose range. This enables generation of diagnostic images from exposures that were previously nondiagnostic on SFR, thus reducing retakes. However, with decreasing detector entrance dose, image noise increasingly hampers the image quality. Conversely, unlike the bl...
Developmental dynamics and survival characteristics of the common horse bot flies (Diptera, Gasterophilidae, Gasterophilus) in desert steppe. The genus Gasterophilus (Diptera, Gastrophilidae) is an obligate parasite of the equine family that causes widespread myiasis in desert steppe. Based on four common naturally excreted Gasterophilus larvae collected systematically in the Karamaili Ungulate Nature Reserve from March to September 2021, this paper studies the population dynamics and ontogenetic laws of horse flies, and discuss the coexistence pattern and population dynamics prediction of horse flies. The results showed that the Gasterophilus larvae had obvious concentrated development period, and the time of population peaks was d...
Corrigendum: Gene therapy approaches for equine osteoarthritis. [This corrects the article DOI: 10.3389/fvets.2022.962898.].
[A Saddle-Horn Injury of the Pelvis]. A saddle-horn injury of the pelvis can be considered a separate category of injuries. They occur during horse riding, when a horse rider hits the horn of the saddle and suffers from anteroposterior compression of the pelvic ring. The hits can cause symphyseolysis or even sacroiliac joint injury, and thus also pelvic ring instability. So far, just a few articles have been published dealing with horse saddle-related injuries. Our report describes a rare case of abnormal haemorrhage in vascular anastomosis called corona mortis. The discussion part is then about appropriate treatment of such injur...
Minimally invasive removal of obstructive ureteral stones by intracorporeal lithotripsy in horses: 3 patients. Three client-owned horses diagnosed with obstructive ureteral stones were referred and treated in a minimally invasive manner by retrograde ureteroscopy in conjunction with electrohydraulic lithotripsy (EHL) or laser Holmium:YAG lithotripsy (HYL). For all 3 horses, additional tests revealed variable degrees of azotemia and ureteral obstruction. Ultrasound examination (2 horses) revealed a loss of cortico-medullary distinction consistent with a chronic nephropathy. Ultrasound-guided biopsy of the right kidney in 1 horse revealed moderate glomerulosclerosis and lymphoplasmacytic nephritis. A sta...
The effect of being housed with a goat on abnormal behavior in horses. Horses in stalls generally remain in single-stall housing, so abnormal behavior can be observed in this management condition. Abnormal behavior can harm the horse's keeper, rider, or even the animal itself. The present study aims to examine the effect of goats on abnormal behaviors in horses. For this purpose, it placed six horses and six goats in the single-stall housing of the horses, one horse and one goat, and monitored them for 45 d. The research was divided into three observation phases during this time: in the first observation, the horses were left alone (0-15 d), in the second obs...
